“Because of the long-term saturation of the soil and the intensity of the rain, the current storm is capable of triggering isolated landslides in landslide prone areas,” the Weather Service said in a special weather statement issued Thursday.

Steep hillsides and coastal bluffs were the most likely areas to see landslides.

Rain from the last few months — December was the second-wettest on record with 11.21 inches — has already saturated the soil, making it unstable, the Weather Service said.

Heavy rains from the storm moving through could loosen soil and debris.

As for temperatures, highs will be near 53 degrees and dropping to the mid-40s through next week.
